Tropical Storm Harvey spun across southeast Texas into Louisiana on Wednesday, sending more people fleeing for shelter after swamping Houston with record rains and flooding that killed at least 35 people and drove tens of thousands from their homes.

The storm has forced 32,000 people into shelters since coming ashore on Friday as the most powerful hurricane to hit Texas in half a century. On Wednesday, it pummeled the coast from Port Arthur, Texas, to Lake Charles, Louisiana.
